1. Sliding bearing
Sliding bearings do not have inner and outer rings or rolling elements, and are generally made of wear-resistant materials. It is often used in low-speed, light-loaded, lubricated, and difficult-to-maintain mechanical rotating parts.
2. Joint bearing
The sliding contact surface of the joint bearing is a spherical surface, which is mainly suitable for swing motion, tilt motion and rotation motion.
3. Rolling bearings
Rolling bearings are divided into radial bearings and thrust bearings according to the load direction or nominal contact angle they can bear. Among them, radial contact bearings are radial bearings with a nominal contact angle of 0, and radial angular contact bearings are radial bearings with a nominal contact angle greater than 0 to 45. Axial contact bearings are thrust bearings with a nominal contact angle of 90, and thrust angular contact bearings are thrust bearings with a nominal contact angle of more than 45 but less than 90.
